Disaster Recovery
Disaster Recovery for EWSD, S12 or other TDM and VoIP exchange systems


In the event of the sudden failure of switches, effective disaster recovery management is essential to make failed telephony services available again promptly. Here, in addition to technical expertise, effective reproduction processes and professional crisis management are critical success factors.

SilverEngine offers 24/7 emergency support independently or in collaboration with strategic technological partners.

Our proven approach

Initially, the service levels for emergency management are coordinated with the customer. Based on these parameters, the process and the responsible persons within the process can be established. The design specifications are also defined and implemented in the setup phase. In this phase, the foundation is laid for effective disaster recovery.

The effectiveness of the disaster recovery process established in collaboration with the customer is tested within the framework of several test runs, before the emergency support is put into operation.


  • Setup and test phase

    Establishment of requirements / service-level agreements
    Definition of the process and the responsibilities
